The indoor air of a hospital is always full bacteria and viruses due to patients with different diseases. These could be highly infectious the people in irrespective their health conditions, hazardous patients, care takers, staff. Thus, keeping good quality very essential operation hospital. This study aims at enhancing ventilation interior lighting hospitals germicidal capabilities. Air disinf...

This review evaluates the applicability and relative contribution of ultraviolet germicidal irradiation (UVGI) to disinfection of air in health care facilities. A section addressing the use of UVGI for environmental surfaces is also included. The germicidal susceptibility of biologic agents is addressed, but with emphasis on application in health care facilities. The balance of scientific evide...

Article history: Received on: 23/06/2016 Revised on: 14/07/2016 Accepted on: 04/09/2016 Available online: 29/11/2016 To avoid skin dryness and irritation encountered with alcohol-based sanitizers, Toddalia asiatica stem bark extract was explored in formulation of a germicidal herbal antiseptic detergent. A L9 (3 4 ) Taguchi Orthogonal Array was used to optimize set factors for design and prepar...

The cytotoxicity of 193 and 248 nm excimer laser radiation was compared to that produced by a germicidal lamp (predominantly 254 nm) using Chinese hamster ovary cells (CHO), and a human diploid fibroblast line, AG-1522A. Excimer laser radiation at 248 nm (3.5 X 10(2) w/m2) and germicidal radiation (5.3 X 10(-5) w/m2) caused toxicity in both cell lines, with the AG-1522A cells (D37 = 7-8 J/m2) b...

Increasing resistances of germs to established antiseptics demand a continuous development of new antimicrobial agents. Therefore, atmospheric pressure plasma was used to produce antimicrobial NaCl-solutions. Its shortand long-term germicidal effects have been investigated by inactivation of Escherichia coli in batches. Liquid changes by plasma exposure that correlate with bacteria inactivation...
